It's a tragedy to be pessimistic rather than optimistic.
Pessimism looks at tough times and assumes darkness, death and hell have won.
But optimism turns to God and remembers the light of the world has already conquered death and hell, and is now establishing His kingdom, waiting for all His enemies to become a footstool for His feet.
“I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life" (Jn.8:12).
